実験手順

To a stirred solution of (E)-(2-chloro-4-(3-(3,5-dichlorophenyl)-4,4,4-trifluorobut-1-en-1-yl)phenyl)methanamine (0.2 g, 0.5 mmol) in CH2Cl2 (5 mL) at 0° C. were added Et3N (0.141 mL, 1 mmol) and ethylisocyanate (0.053 g, 0.75 mmol), and the reaction mixture was stirred for 1 h at 0° C. The reaction mixture was diluted with CH2Cl2. The organic layer was washed with H2O and brine, dried over Na2SO4, and concentrated under reduced pressure. Purification by column chromatography (SiO2, 100-200 mesh; 30-50% EtOAc in hexane) afforded the title compound as a solid (0.141 g, 60%): mp 177-178° C.; 1H NMR (400 MHz, CDCl3) δ 7.58 (m, 2H), 7.41 (m, 3H), 7.24 (m, 1H), 6.53 (d, J=16.0 Hz, 1H), 6.35 (dd, J=16.0, 8.0 Hz, 1H), 4.70 (br s, 1H), 4.43 (s, 2H), 4.08 (m, 1H), 3.21 (m, 2H), 1.25 (m, 3H); ESIMS m/z 463 ([M−H]−).
